Make moss take a hike

I have a patio that is covered by a large deck. Every fall, this porch is covered with bright-green moss. What can you suggest that will remove this?

A tried-and-true Heloise hint! Moss can be ugly, but it's easy to scare away and keep away. First, scrub off as much as possible with a brush or broom. Then kill it using full-strength (5 percent), cheap white or apple-cider vinegar. Just pour and let it sit about 30 minutes, scrub and let dry. No need to rinse.
